Hoses, metal pipes and some clamps from the auxiliary water pump to the monovalve and those into the firewall. Includes mono valve housing.
Only one is available as shown. Good used pipes and hoses as shown. The hoses are still soft with no evidence of cracking. The pipes are reasonably clean with no evidence of any severe rust. These will not fit those 1984 and 1985 diesels with the trap oxidizer.
